I am considering a new, simpler, and easier to maintain head
arrangement that would include 1) manual freshwater flushing,

And how do you plan to accomplish that if you install a toilet designed
to pull in sea water? 'Cuz no toilet designed to use raw water (sea,
lake, river etc) should ever be connected to the onboard fresh water
supply...it cannot be done without risk of e-coli contamination of the
potable water, damage to the toilet, or both...and every toilet mfr
specifically warns against it. Only toilets designed to use pressurized
flush water can safely be connected to the fresh water system...and
there is no manual toilet designed to use pressurized flush water.

2) no
macerator, 3) no Y valve, 4) Lavac or Skipper toilet, 5) just a
freshwater intake, a vent, and a deck pump-out, and 6) high-quality
hoses.


I am thinking about ordering a new Valiant 42. This set-up would
eliminate two holes in the boat, right?

Only one if you tee the head intake into the head sink drain line.

However sending everything to the tank with no way to flush directly
overboard or dump the tank at sea(flushing directly overboard is a much
better choice...no chemicals, small amounts instead of tankfuls) will
drastically reduce your cruising range...you can only stay out till the
tank gets full. And holding tanks are FAR from maintenance free.

And, this would seem to be a
higher quality alternative to what you recommended a few strings up: a
permantent porta-potti with pump-out feature.

More expensive, more complex, but not necessarily better
quality...Quality is relative. Is a Lexus better quality than bicycle?
No...that's comparing apples to tennis balls.

Simple and easy to
maintain.

If you think a tank is easy to maintain, talk to a few people who've
done it for a while. Tanks are a major PITA!
